METALLIC COLUMN.

SPECIFICATION forming part of Letters Patent No. 631,655, dated August 22, 1899.

Application filed January ZO, 1896. Serial No. 576,209. (No model.)

To @ZZ whom it may concern:

Be it known that I, FREDERICK C. NOBLE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented a new and Vuseful Metallic Column, of which the following is a specification.

This invention relates to improvements in metal columns designed and particularly adapted for structural purpose in the construction of'buildings.

Primary objects of the invention are to produce a hollow, square, or rectangular column of simple construction having plane exterior and interior faces, thus providing for making beam-and-girder connections thereto, either in line with the center ot' the column or eccentric thereto, and for increasing the sectional areas of columns by securing reinforcing-plates, either plain plates, channels, or angle-plates, to the interiors thereof; to provide a column in which the metal will be disposed at the greatest possible distance from the neutral axis thereof, thus producing a column of maximum strength with a minimum amount of metal, and to produce a column,

`the sectional area of which may be conveniently varied by changing the thickness thereof, thus rendering it possible to make the beams and girders connecting the columnsin a building exactly alike in all of the floors while varying the strength of the columns to conform to the varying loads which they carry,

thus very materially simplifying the detail-1 ing of tall buildings in which the loads on the columns vary widely from the bottom to the top of the structure and correspondingly re-A ducing the expense thereof.

A column embodying my invention consists of the various features, combinations of features, and details of construction hereinafter described and claimed.

In the accompanying drawings a column embodying my invention is fully illustrated.

Figure l is a side elevation of a column embodying my invention in its simplest form. Fig. 2 is a plan section taken on the line 2 2 of Fig. l, showing one means for making eccentric connections thereto or connections of girders containing two beams. Fig. 3 isa plan section taken on the line 3 3 of Fig. l, showing one means for making connections for l beams located in line with the neutral axisof the column. Fig. 4 is a side elevation of a column embodying my invention, showing ordinary angle-bars combined with the structural members shown in Fig. l. Fig. 5 is a plan section thereof on the line 5 of Fig. 4. Fig. 6 is a plan section thereof on the line G G of Fig. 4, and Fig. 7 is a plan section of a special form of column embodying my invention.

A column embodying my invention comprises, essentially, double angle-bars A, each consisting of an intermediate web a, the exterior surface of which forms a single right angle and the interior surface vof which is preferably parallel with the exterior surface, and flanges ct', one at each edge of said web a, the outer faces of said flanges being at right angles to each other and to the outer surfaces of the adjacent sides of the web a.

The members A are secured together lto form my improved column by means of bolts or rivets inserted through the iianges 01,', as clearly shown in Figs. l and 3 of the drawings, the relation thereof being such that the exterior surfaces of adjacent sides of the webs a of adjacent members Awill be in the same plane and will form one side of the column. It is thus obvious that a square or rectangular column will be formed, the faces or sides of which will be plane, and that each sido will have a central longitudinal rib A' extending the entire length thereof. It is also obvious that the column Will`be hollow, and that when the exterior and interior surfaces of the webs a are parallel with each other the inner sides thereof will be plane and will define a square or rectangle.

Central beam-and-girder connections are ordinarily made by means of angle-plates a3, bolted or riveted to the ribs A' of the column,

to which the beams and girders are attached IOO directly to the faces of the column at the sides of the ribs A', as clearly shown in Fig. 2 of the drawings.

lVhen desired, the sectional area of my improved column may be conveniently and economicallyincreased b ysec u rin g a strengthening plate or plates A2 to the interior plane surfaces thereof. These plates may be either plain plates, as shown in diagram in Fig. 3 of the drawings, or they may be channels or angles, as shown in diagram in Figs. 5 and 6 of the drawings, respectively.

It is obvious that by means of a column of the described construction I effect all of the Objects of my invention hereiubefore enu merated and produce withal a relatively very simple and cheap column.

A further very advantageous feature of a column embodying my invention is that the members thereof are rigidlysecured together, so that a load ou one of said members will be distributed, each member receiving and sustaining a portion of the load.

I claim- 1. A metal column comprisingr a plurality of double angle-bars, each consisting of an intermediate web, the exterior surface of which forms a single right angle, each of the faces of which is flat throughout and flanges at both edges thereof, the outer faces of the flanges of each member being at right angles to each other and to the exterior surfaces of the adjacent sides of the intermediate web thereof, said double angle-bars being secured together to form a rigid structure by means of bolts or rivetsinserted through said flanges, the relation being such that the exterior surfaces of adjacent sides of the intermediate webs of adjacent members will be in the same plane, and connected flanges forming a rib or ribs, which extend longitudinally the entire length of said column, substantially as described.

2. A metal column comprising a plurality of double angle-bars, each consisting of an intermediate web, the exterior surface of which forms a single right angle each of the faces of which is flat throughout and the interior surface of which is parallel with the exterior surface, and flanges at both edges of said intermediate web, the outer surfaces ofthe flanges of each member being at right angles to each other and to the exterior and interior surfaces of the adjacent sides of the intermediate web thereof, said double angle-bars being secured together to form a rigid structure by means of bolts or rivets inserted through said flanges, the relation being such that the exterior and interior surfaces of adjacent sides of the intermediate webs of adjacent members will be in the same planes,connected flanges forming a rib or ribs, which extend longitudinally the entire length ofthe column and a strengthening plate or plates secured to an interior plane side or sides of the column, substantially as described.

3. A metal column comprising four double angle-bars, each consisting of an intermediate web, the exterior surface of which forms a single right angle, each of the faces of which is flat throughout and flanges at both edges thereof the outer faces of the flanges of cach member being at right angles to each other and to the exterior surfaces of the adjacent sides of the intermediate web thereof, said double angle-bars being secured together to form a rigid, square or rectangular structure by rivets or bolts inserted through said flanges, the relation being such that the exterior surfaces of adjacent sides of the intermediate webs or adjacent members will be in the same plane, and connected flanges forming ribs which extend longitudinally the entire length of said column, substantially as described.

4. A metal column comprising four double angle-bars, each consisting of an intermediate web, the exterior surface of which forms a single right angle each of the faces of which is flat throughout and the interior surface of which is parallel with the exterior surface, and flanges at both edges of said intermediate web, thelouter surfaces of the flanges of each member being at right angles to each other and to the exterior and interior surfaces of 9 the adjacent sides of the intermediate web thereof, said double angle-bars being secured together to form a rigid, square or rectangular structure by means of rivets or bolts inserted through said flanges, the relation being such that the exterior and interior surfaces of adjacent sides of the intermediate webs of adjacent members will be in the same planes, connected flanges forming ribs, which extend longitudinally the entire length of the column and a strengthening plate or plates secured to an interior plane side or sides of said column, substantially as described.

In testimony that I claim the foregoing as my invention I hereunto set my hand this 8th day of January, 1896.

FREDERICK C. NOBLE.
